POULTFY-BROODER.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed July 3, 1906. Serial No. 324,634.

Be it known that I, HENRY H. DAMMAN, a citizen of the United States, residing at Kiowa, in the county of Barber and State of Kansas, have invented new and useful Improvements in Poultry-Brooders, of which the following is a specification.

This invention relates to a chicken broeder, and the primary object of the same is to provide simple and effective means in connection therewith for permitting the fumes and smoke of the heating medium or lamp to escape from the brooder without permeating or affecting the interior of the structure and also to provide a device of this class which can be readily handled and will be especially advantageous for the purposefor which it has been devised.

The invention consists in the construction and arrangement of the several parts which will be more fully hereinafter set forth.

In the drawings, Figure 1 is a front elevation of a brooder embodying the features of the invention. Fig. 2 is a longitudinal vertical section of the same. tal section therethrough.

Like characters refer to like parts throughout the several views.

The numeral 1 designates a surrounding or inclosing casing which may be made of suitable material and has supporting legs 2. In the center' of the bottom of the casing an opening 3 is formed for the projection therethrough of a chimney 4 of a lamp 5, the latter being held by a support 6 having angular 'flanges 7 at the upper terminals of the sides to slidingly engage the guide strips 8 secured to the under side of the bottom of the casing. The support 6 is slidable inwardly and outwardly with relation to the guide strips 8 so -as to permit the removal and assemblage of the lamp body particularly in relation to the bottom of the casing. The support 6 is fully closed at the sides and bottom and open at opposite ends and the opening 3 is large enough to permit air to be indrawn therethrough to increase the heat currents.

At an elevation above the bottom of the casing and on the interior of the latter are supporting rails or ledges 9 secured at the front and back to hold a removable brooding chamber 10 which is open at the front and back and closed at the ends and top and bot- Fig. 3 is a horizontom. Secured to the center of the bottom of this brooding chamber is a metal shield 11 which is disposed directly over the chimneyT 4 of the lamp, said shield being hollow and permitting the air and heat to circulate therethrough and operating to prevent the bot-v tom of the brooding chamber from being burned or scorched in view of its close proximity to the heating device or lamp. Extending vertically through the brooding chamber are circulating tubes 12 which are open at top and bottom, but have no communication whatever with the interior of the brooding chamber. On the brooder a removable cover 13 is arranged and has depending escape pipes 14 which permit the heat currents to pass out through the top of the brooder and rising from the center of the brooding chamber is a Ventilating pipe 15, which also removably engages an opening 18 in the cover 13. T he brooding chamber is of less length than the interior of the casing 1 and passages 16 are thus formed at the ends for the circulation upwardly therethrough of the heat currents so that the brooding chamber will be thoroughly heated and the temperature thereof maintained uniformly both at the ends and intermediate portions.

The front of the casing 1 has an opening 19 formed therein and on the exterior of the front are upper and lower guides 20 in which a slide door 21 is mounted and operates to close the opening 19, or when pulled back, to

give access to the interior of the brooder especially to the brooding chamber 10. In the front of the casing 1 are also ventilating openings 22 which have slide covers 23 norniallj)T depending thereover, said covers being of the gravitating type and operating to immediately close the openings 22 when released. IVhen the covers 23 are elevated and the openings exposed, the air is permitted to enter the interior of the brooder and temper the latter.

At the front of the brooder below the door 21 a ledge or shelf 24 is provided of suitable dimensions to permit the chickens to pass out thereonto for feeding purposes or for limited exercise and airing. The door 21 will be constructed with a glass panel 25 to admit light to the interior of the brooder. The construction of the door, as clearly shown by Fig. 1, as well as the Ventilating openings and IOO slide covers is duplicated at the front and back of the brooder and likewise the supporting shelf 24 will also be added onboth sides or at the front and rear of the casing. This is a con venient arrangement, in view of the fact that the brooder is rendered accessible from either side, and furthermore the chickens may be let out from both sides and fed or otherwise benefited without too much crowding or increasing the shelves 24 to too great dimensions. It is proposed to attach and seeure each shelf or platform 24 by any suitable means.

The brooder will be found exceptionallyT advantageous and useful, and it is proposed to modify the proportions, dimensions and minor details within the scope of the invene tion to accommodate various applications thereof.

What l claim is:

l. A brooder having an inclosing casing with door openings at the front and back, doors movably operating over the said openings, a heating device projecting through the bottom of the casing, a brooding-chamber removably mounted within the casing and of less length than the latter and having pipes extending vertically therethrough, escape pipes in the top of the casing and an escape pipe between the top of the brooding-chamber and said casing top.

2. A brooder having an inolosing casing with heating means applied to the bottom thereof and door openings in the front and rear of the same, platforms secured to the front and rear of the easing adjacent to the door openings, the front and rear of the oasing also having vent openings therein, closing devices cooperating with the door and ventilating openings` a brooding-chamber re movably mounted within the casing and of less length than the latter, said broodingchamber having a metal shield or deflector on the bottom thereof over the heating means and also provided with pipes extending vertically therethrough near the ends and terminating at the top and bottom of the same, Ventilating pipes in the top of the inclosing casing and an escape pipe between the said top and the top of the broodingchamber.

In testimony whereof, I affix my signature in presence of two Witnesses. 1
